Example 1

As shown in fig. 1, the present invention provides a textile motor 10 with high braking performance, including: the housing 11, the rotary shaft 14, the stator 16, and the rotor 19 are installed. The rotary shaft 14 is rotatably connected to the mounting housing 11. The stator 16 is fixedly mounted to the mounting housing 11. The rotor 19 is fixed to an end of the rotating shaft 14. The stator 16 has an iron core therein. A coil 18 is wound around the outer periphery of the core. The periphery of the rotor 19 is uniformly distributed with magnetic steels 191 for pushing the rotor 19 to rotate under the action of magnetic force. The stator 16 is disposed around the rotor 19 and forms a rotation gap 20 with the rotor 19. The outer periphery of the rotor 19 is fitted with a support bearing 21 for supporting the stator 16. The end of the stator 16 remote from the mounting housing 11 is provided with a brake coil 22. The end of the rotor 19 remote from the mounting housing 11 is provided with a brake disc 23. The brake disc 23 is provided with a brake 24 on a side facing the brake coil 22 for engaging the brake coil 22.

The textile motor 10 with high braking performance is additionally provided with the supporting bearing 21 between the stator 16 and the rotor 19, so that the stability of the gap of the rotating gap 20 can be ensured, and the motor is prevented from being damaged due to friction between the stator 16 and the rotor 19 of the motor. The support bearing 21 also serves as a mounting location, making the mounting between the rotor 19 and the stator 16 more convenient, without the need for a housing of the textile machine to be located.

The textile motor 10 with high braking performance is additionally provided with the brake 24 at the end part of the rotor 19, so that the braking current of the motor is greatly reduced during high-speed braking, the frequency converter can be changed into a lower type, and the cost is saved. The reduction of the motor brake current greatly reduces the demagnetization of the magnetic steel 191 of the motor, and the risk of demagnetization is reduced, so that the service life of the motor is longer.

In addition, the prior direct drive motor keeps braking output by the frequency converter, and when the frequency converter fails, the direct drive motor does not keep braking, so that the textile machine can rotate when high torque is kept, and the safety cannot be guaranteed. After adding stopper 24, stopper 24 mechanical end is equivalent to an inertia dish, and under the very big condition of weaving machine running torque deviation, can make the more steady of rotational speed through the inertia balance of stopper 24 to can dwindle under the very big condition of running torque deviation and the target rotational speed between the error, the operation of weaving machine is more stable like this, and efficiency is higher.

That is, when the limit bearing is installed, the rotor 19 is fixedly installed on the outer circumference of the rotating shaft 14, and then the support bearing 21 is inserted into the limit groove 161, so that the axial position of the support bearing 21 can be limited.

As a specific embodiment, the stator 16 is formed with a mounting groove 162 above the stopper groove 161. The mounting groove 162 is used to mount the brake coil 22.

Further, the brake 24 and the brake disc 23 constitute a mounting unit and are formed with a through hole 25 together, and the brake 24 and the brake disc 23 are fixedly attached to the rotor 19 by screws passing through the through hole 25 and screwed into fixing holes 193 formed in the rotor 19. After the installation is completed, the distance between the brake 24 and the stator 16 is less than the radius of the brake coil 22, so that the brake coil 22 is prevented from being separated from the installation groove 162, and the reliability of the installation structure is high. The motor is powered on, the brake coil 22 is powered off, the electromagnet 24 is separated from the brake coil, and the machine runs. After the motor is powered off, the brake coil 22 is powered on, the electromagnet 24 is attracted by the brake coil 22, and the machine keeps braking force.

As a specific embodiment, the mounting housing 11 is formed with a shaft hole 111 for passing the rotating shaft 14 therethrough, the end of the shaft hole 111 is provided with a support frame 12 for rotatably supporting the rotating shaft 14, the rotating shaft 14 passes through a through hole 25 formed in the support frame 12, and a rotating bearing 13 is provided between the support frame 12 and the rotating shaft 14 for rotatably supporting the rotating shaft 14.
